Si loo falanqeeyo taraafikada shabakadda, waxaa lagama maarmaan ah in loo diro xirmada shabakadda NTOP/NPROBE ama Qalabka Ilaalinta iyo Ilaalinta Shabakadda Ka Baxsan. Waxaa jira laba xal oo dhibaatadan:
Port Mirroring(sidoo kale loo yaqaan SPAN)
Shabakadda Taabo(sidoo kale loo yaqaan Tap-ku-dhufashada, Tabaha Isku-darka, Taabka Firfircoon, Taabka Copper, Taabka Ethernet, iwm.)
Kahor intaadan sharaxin farqiga u dhexeeya labada xal (Port Mirror and Network Tap), waxaa muhiim ah in la fahmo sida Ethernet u shaqeeyo. Marka la joogo 100Mbit iyo wixii ka sareeya, martigaliyayaasha ayaa inta badan ku hadla laba-duplex, taasoo la macno ah in hal marti-geliyaha uu soo diri karo (Tx) oo uu heli karo (Rx) isku mar. Tani waxay ka dhigan tahay in xadhkaha 100 Mbit ee ku xidhan hal marti-geliyaha, wadarta xadiga taraafikada shabakada ee hal marti-geliyaha soo diri karo/heli karo(Tx/Rx)) waa 2 × 100 Mbit = 200 Mbit.
Muraayadda dekeddu waa ku celcelin firfircooni baakidh ah, taas oo macnaheedu yahay in aaladda shabakadu ay jidh ahaan mas'uul ka tahay koobiyaynta baakadda muraayadda muraayadda ah.
Tani waxay ka dhigan tahay in aaladdu ay tahay inay qabato hawshan iyadoo la adeegsanayo kheyraad (sida CPU), labada jihooyinka taraafikada ayaa lagu soo celin doonaa isla deked isku mid ah. Sida hore loo soo sheegay, in A full duplex link, tani waxay ka dhigan tahay in
A -> B iyo B -> A
Wadarta A kama badnaan doonto xawaaraha shabakada ka hor inta uusan dhicin baakadu. Tani waa sababta oo ah jir ahaan ma jirto meel bannaan oo lagu koobi karo baakadaha. Waxaa soo baxday in muraayada dekeddu ay tahay farsamo weyn maadaama ay samayn karaan furayaal badan (laakiin maaha dhammaantood), sababtoo ah inta badan furayaasha leh cilladda baakidhka luminta, haddii aad la socoto xiriirinta ka badan 50% culeyska, ama muraayadda dekedaha ku xidha deked dheeraysa (tusaale muraayada 100 Mbit dekedo dulsaar 1 Gbit ah). Ma aha in la sheego in muraayada baakidhku ay u baahan karto is-dhaafsiga agabka furayaasha, taas oo laga yaabo in ay ku shubto qalabka oo ay keento in wax-qabadka beddelka uu hoos u dhaco. Ogsoonow inaad ku xidhi karto 1 deked hal deked, ama 1 VLAN hal deked, laakiin guud ahaan ma koobi kartid dekedo badan 1. (Sidaa muraayada baakadka ah) ayaa maqan.
Shabakadda TAP (Barta Gelitaanka ee Terminalka)waa qalab qalabaysan oo dhamaystiran, kaas oo si dadban u qabsan kara taraafikada shabakada. Waxaa caadi ahaan loo isticmaalaa in lagula socdo taraafikada inta u dhaxaysa labada dhibcood ee shabakada. Haddii shabkada u dhaxaysa labadan qodob ay ka kooban tahay fiilo jireed, shabakad TAP ayaa laga yaabaa inay noqoto habka ugu fiican ee lagu qabto taraafikada.
Shabakadda TAP waxay leedahay ugu yaraan saddex dekedood: deked A, deked B, iyo deked kormeere ah. Si qasabadda loo dhigo inta u dhaxaysa dhibcaha A iyo B, fiilada shabakadda ee u dhaxaysa barta A iyo barta B waxaa lagu beddelayaa laba xabbo, midna wuxuu tegayaa dekedda TAP's A, ka kalena wuxuu tegayaa dekedda TAP's B. TAP-du waxa ay gudbisaa dhammaan taraafikada u dhexeeya labada goobood ee shabakada, si ay wali isugu xidhan yihiin. TAP waxay sidoo kale koobiyaysaa taraafikada dekeddeeda kormeeraha, si ay awood u siiso aaladda falanqaynta inay dhageysato.
Shabakadda TAP-yada waxaa sida caadiga ah isticmaala la socodka iyo ururinta aaladaha sida APS. TAP-yada sidoo kale waxaa loo isticmaali karaa codsiyada amniga sababtoo ah maaha kuwo aan qarsoodi ahayn, lagama ogaan karo shabakada, waxay la macaamili karaan shabakadaha buuxa iyo kuwa aan wadaagin, waxayna inta badan dhex maraan gaadiidka xitaa haddii tuubadu ay joojiso shaqada ama lumiso awoodda. .
Maadaama aanay dekedaha Network Taps-ka helin balse ay gudbiyaan oo keliya, shixnaduhu ma laha wax calaamad ah cidda fadhida dekedaha gadaasheeda. Natiijadu waxay tahay in ay ku baahiso baakooyinka dhammaan dekedaha. Sidaa darteed, haddii aad ku xidhid qalab aad la socodka in dabada, qalabka sida heli doontaa dhammaan baakadaha. Ogsoonow in habkani uu shaqeeyo haddii qalabka kormeerku uusan u soo dirin wax baakidh ah furaha; haddii kale, daaranku wuxuu u qaadan doonaa in baakadaha la taabtay aysan ahayn qalabkaas. Si taas loo gaaro, waxaad isticmaali kartaa fiilada iskuxiran ee aadan ku xirin fiilooyinka TX, ama waxaad isticmaashaa shabakad IP-less (iyo DHCP-yar) oo aan gudbin xirmooyinka gabi ahaanba. Ugu dambeyntii ogow in haddii aad rabto inaad isticmaasho tuubada si aadan u lumin xirmooyinka, markaas ama ha isku darin tilmaamaha ama isticmaal furaha halka jihooyinka la taabtay ay ka gaabinayaan (tusaale 100 Mbit) ee isku darka dekedda (tusaale 1 Gbit).
